HD1 — Oryza sativa Indica Group

Summary

BGIOSGA003030 (HD1) on Indica rice chromosome 1 encodes a protein with histone deacetylase domains and is annotated with histone deacetylase binding, transcription corepressor activity, and structural constituent of chromatin functions. The gene is associated with stress responses including salt and osmotic stress resistance, as well as growth, root development, and seed traits. It has been linked to biological processes such as tubulin deacetylation, negative regulation of seed maturation, fruit abscission, and regulation of multicellular organismal development. Localization evidence places the product in HDAC and PRC2 complexes, condensed chromosomes, and the nucleolus. The gene is also connected to traits including floral organ length, panicle number, spikelet fertility, and metabolite content. Studies of related genes in other species link the family to flowering transition, flower development, seed viability, and abiotic stress tolerance.
